Targ S.M. 1989 C2 option 33

The structure consists of a rigid angle and a rod, which at point C are either hinged to each other or freely resting on each other. The structure is acted upon by: a pair of forces with a moment M=60 kNm, a uniformly distributed load with intensity q=20 kN/m and two forces. Determine the bond reactions at points A, B, C. For final calculations, take a=0.2m.
Given: K: F₂= 20kN; α₂= 30⁰; H: F₄ = 40kN; α₄ = 60⁰; C.L.
